(2-Methoxyphenyl)ethynes react with aryl or alkyl halides to give disubstituted alkynes which are converted into the corresponding 2-substitutedbenzo[b]furans on treatment with lithium iodide in 2,4,6-trimethylpyridine.

in the synthesis and evaluation of nonclassical inhibitors, which could enter cells via passive diffusion and are not substrates for folypolyglutamate synthetase. A series of eight nonclassical 6-substituted 2-amino-4-oxo-pyrrolo[2,3-d]pyrimidines 2a-2h were designed as potential inhibitors of thymidylate synthase. The synthesis of the target compounds 2a-2h was achieved via regioselective iodination
